The thing with spending just a few weeks with a loaner Nexus 5, Google and LG's Android 4.4 KitKat reference device, is that I'm not able to enjoy what's easily this phone's most attractive feature – the fact that it only costs $349 unlocked from the Google Play store in the US. That's not to say that there isn't plenty more to love about the Nexus 5. It comes with a great screen, quality software upgrades and plenty of hefty components that allow it to compete with any other flagship phone out there today.
